IMPROVEMENT IN ROAD-SCYRAPERS.

v Specification forming part of Letters Patent No. 222,878, dated December 23, 1879; application filed August 5, 1879.

To all whom it may concern.- F, which are attached to the rear side of the Be it known that I, SAMUELH. DUDLEY, of

State of Connecticut, have invented a new and useful Improvement in Road-Scrapers, of which the following is a specification.

Figure 1 is arear view of the scraper. Fig. 2 is a cross-section of the same, taken through the line mm, Fig. 1. Fig. 3 is a detail perspective view of the guard-bar and staple.

,The object of this invention is to improve the construction of the scraper for which Letters Patent Nos. 11,021 and 37 ,498 were granted to me June 6, 1854, and January 27, 1863, in such a wayas to prevent the plank from being split, and from being worn by the draw-rods.

The invention consists in the combination of the guard-bars having their upper ends bent forward at right angles to fit into the notches in the upper edge of the plank, and having sockets formed in their lower parts to receive the rear ends of the draw-rods, with the plank, the draw-rods, and the staples of the scraper, as hereinafter fully described.

Similar letters of reference indicate corre-' sponding parts.

A represents the plank of the scraper, to the lower part of the forward side of which is attached a steel plate, B. The lower edge of the plate B projects below the lower edge of the plank A, to act upon the ground and receive the wear.

To the rear side of the plank A are attached the handles C, by means of which the scraper is guided and controlled. To the handles C is attached a bar, D, which is placed a little above and parallel with the upper edge of the plank A. In the upper edge of the plank A,

near its ends, are formed notches through which the draw-rods E pass.

The rear portion of the draw-rods E are bent into semicircular form, and have hooks formed upon their rear ends to hook into the staples plank A, a little below its central line, about all of which there is nothing new, the same being shown and described in my Patent of January 27, 1863, No. 37,498.

To the rear side of the plank A are attached guard-bars G, of a length about equal to the width of the said plank A. The upper ends of the guard-bars G are bent forward at right angles to fit into and form a facing for the bottoms of the notches in the upper edge of the plank A, to prevent the said plank from being worn by the draw-rods E.

In the parts of the guard-bars G that pass through the staples F are formed sockets to receive the rear ends of the draw-rods E, to

' receive the draft-strain. The bars G preconveniently attached and detached, as may be required.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination of the guard-bars G, having their upper ends bent forward at right angles, to fit into the notches in the upper edge of the plank A, and having sockets formed in their lower parts, to receive the rear ends of the draw-rods E, with the plank A, the I draw-rods E, and the staples F of the scraper, substantially as herein shown and described.
